It's not on the approved list; so it'll need to be acquired via LEO sale, PPT, out-of-state intra-familial gift or as a dimensionally compliant single-shot pistol.

Heard it's on par with the GSG 1911 .22LR.

IIRC, it also has a threaded barrel and the way the gun is put together makes switching out the barrel (for SSE) difficult.
Picture from 1911.org, not the barrel is attached to the frame:

I have yet to run across a dealer that can get it to work here in CA.
IF you find a dealer who says they can SSE it I am interested, especially if it means splitting the cost on an SSE barrel.
